As I like to say, it's what you do with the tech that's more important than the tech itself.

NASA sent men to the moon and brought them back safely to the Earth with less total computing power than I have in my Asus TF700 tablet..... which I use mainly to look at The Chive and post status updates on Facebook.

That's awesome - a ton of computing power = 5 Mb in '56. Today that same weight gets you at least into the hundreds of Petabytes range.

As far as being an old geek, I may not be quite as old as you, but I do have to admit that I fondly remember talking about the future of computers with my future father in law, back when this was his portable work computer.

I went to work in 1968 for a large steel mill; their payroll department worked in a massive room and had over 100 people in it. During the time I was in the Army they computerized their pay system. When I saw that room again there were a half dozen or so clerks left with some supervisors. They also eliminated clerical jobs throughout the plant. A buddy of mine became a cobol (sp) programmer. I remember visiting him in a small I.T. office (It wasn't called IT then).It had quite a few keypunch operators grinding away on those cards like worker bees.
